Hi there! I see you’re having trouble with the Sweet Dreams app—it’s not receiving readings, shows no display, and when you click Stop, it just spins but eventually the reading comes through when you close it. Let’s get to the bottom of this together.

To clarify, is the app installed on your Mac with OS X 10.15.7, and are you using it to connect to a CGM device like a Dexcom or FreeStyle Libre? Also, do you notice this issue right from app launch, or after some time of usage?

Meanwhile, here’s a step-by-step approach we can try to resolve this:

1. Restart the App and Mac
- Quit the Sweet Dreams app completely (use Cmd + Q or right-click the app icon and select Quit).
- Restart your Mac to clear temporary caches and refresh system processes.
- Open the app again and see if it receives readings normally.

2. Check App Permissions and Network
- Make sure the Sweet Dreams app has any necessary permissions (like Bluetooth or network access) enabled in your Mac’s System Preferences > Security & Privacy.
- Sweet Dreams needs to communicate with the CGM device or its cloud server, so ensure your internet connection is stable.

3. Update the App
- Check the Mac App Store or the developer’s website for any updates to Sweet Dreams. Sometimes issues like spinning wheels and no data arise from outdated versions.

4. Clear App Cache or Data
- The issue might be from corrupted data within the app. Unfortunately, macOS apps don’t always have direct cache clearing, but you can try deleting the app preferences file:
- Go to Finder > Go > Go to Folder, then enter ~/Library/Preferences/
- Look for files related to Sweet Dreams (usually something like com.sweetdreams.app.plist) and move them to Trash.
- Restart the app (note: this may reset your settings).

5. Reinstall the App
- Delete Sweet Dreams completely and reinstall it fresh. That can fix any corrupted app files.

6. Check CGM Device Connectivity
- If the Sweet Dreams app depends on a CGM device, ensure the device is paired and working correctly on your Mac or iPhone, depending on your setup.

Since you mention the reading does eventually come once you close the app, it sounds like the app may be struggling to refresh or update the live display interface.

If you’ve already tried any of these steps, could you let me know which ones so we can dig deeper? Also, knowing what CGM device you connect to will help me suggest more specific fixes.

I’m here to help get your Sweet Dreams app back to showing those important readings smoothly!
